To all whom it may concern:

Be it known that I, EATON D. SARGENT, a citizen of the United States,residing at Y Vinchendon, in the county of \Vorcester and State ofh/Iassachusetts, have invented new and useful Improvements in Freezers,of which the following is a specification.

The present invention relates to improvements in freezers, and moreespecially in the construction of the outer or ice receptacle, and ofthe gearing frame. Its primary object comprehends the following: theproduction of an extremely simple, inexpensive and efficient apparatusof the type specified constructed in such a manner that the innerreceptacle, or freezer proper, is held firmly in position by the gearingframe, which latter is itself locked in place by the action of thefirst-mentioned receptacle, thereby obviating accidental displacement ofsaid frame and, in consequence, of said inner receptacle and the dashermechanism associated with the same.

A structural embodiment of the invention is illustrated in theaccompanying drawings, but no limitation to the precise form of theelements and features shown therein is contemplated or intended, sinceequivalent or analogous parts or features may obviously replace thesame.

Of the said drawings: Figure 1 is a perspective view of the improvedfreezer, with the cover and gearing frame removed. Fig.

2 is a vertical sectlonal view showing the initial position of thegearing frame incidental to its attachment. Fig. 3 is a verticalsectional view showing said frame in position for operation. Fig. 1 is afragmental side elevation of the upper portion of the freezer.

Reference being had to said drawings, and

' to the characters marked thereon, A indicates, in a general manner,the outer or ice receptacle, B the cover therefor, C the innerreceptacle or freezer proper, D the gearing frame, and E the dashermechanism.

The outer receptacle A is constituted by a suitable sheet metal can ofcylindrical shape, provided with a seat 1 and an opening 2 formedtherein adjacent its upper edge and located diametrically opposite eachother.

In the construction illustrated, the aforementioned seat is shown as inthe form of a continuous bead, and as intersected by a short verticalslot 3 which extends above and below the same and opens through theupper edge of the can. The bottom of said can is inwardly dished to aslight extent, as indicated by the numeral 4, the dished portion beingformed at its center with a bearing 5 which receives a suitable pivot (3provided upon the bottom of the inner receptacle 0.

Seat 1 and opening 2 above referred to, serve to support the gearingframe D. This element, in the present instance, is composed of thefollowing integrally-connected parts or portions, viz., a flat bar orstrap-like portion 7 provided at its outer end with a reduced terminal 8and at its inner end with an upstanding projection or boss 9, a skeletonor open portion 10 of substantially annular shape adjacent said boss, acatch 11 located at the opposite end of the frame from the bar orstrap-like portion 7, and a web 12 connecting said catch and theskeleton portion 10. The boss 9 is formed with an interiorlydocatedsocket 13 which conforms to the shape of the square or otherwiseirregularly shaped end 14: of the dasher shaft 15, adapted for receptiontherein, while the catch and skeleton portions 11 and 10 are formed withalining openings for the passage of the ends of the drive shaft 16, saidshaft carrying at its inner end a gear 17 arranged to mesh with anddrive a gear 18 fast upon the cover 19 of the inner receptacle C. Thedrive shaft is designed for operation by means of an operating handle 20of suitable construction, adapted for attachment to the outer endthereof. The dashers for agitating the contents of the inner receptaclemay be of any preferred type and may be connected to the dasher shaft 15in any desired manner. They form no part of this invention, and, hence,require no extended description.

The catch 11 of the gearing frame is designed for cooperation with andfor reception in seat 1. To this end, the upper portion of said catch isextended laterally, so as to form a shoulder, ledge or flange 21, whichis given a slightly arcuate form, so as to enable it to conform exactlyto the shape of said seat, wherein it is adapted to fit, (see Fig. 3).For the same reason, the front face of its body portionv is likewiseconvexed. The terminal lug 8 provided at the opposite end of said framefrom the catch is of such a size and shape as to admit of its insertionthrough opening 2. The distance between the arcuate outer edge of theshoulder 21 and the shoulder or shoulders 22, resulting from theformation of lug 8, slightly exceeds the diameter of the can, as will beapparent from an inspection of F i 2. Consequently, when lug 8 isinserted dirough opening 2, incldental to the attachment of the gearingframe in place, and shaft 16 is slipped through slot 3, shoulder 21 willrest upon the upper edge of the can and be prevented from engagement inseat 1. To effect such engagement, it is, therefore, necessary toslightly elongate the can in the direction of the frame: this mayreadily be accomplished by exerting downward pressure upon handle 20,which has been previously shifted mto the position shown in Fig. 2,whereupon the can edge directly adjacent the catch will be expanded orforced outwardly until shoulder 21 comes into alinement with seat 1 andis received therewithin. When this takes place, it will be apparent thatthe inherent resilience of the can will have the effect of holding saidshoulder in said seat, thereby locking the frame in position, said framein turn effecting the retention of the inner receptacle C in place. Itwill also be seen that the lower portion of slot 3 will be closed by thebody portion of catch 11, as shown in Fi 4.

Where a cover of the type shown in Figs. 1 and 3 is employed, it will beseen that the gearing frame is additionally locked agalnst displacement,since the peripheral side wall 23 of said cover will project downwardlyacross and fit directly against the outer face of the can, thusobviating the possibility of upward movement of shaft 16 so long as thecover is in use. Said wall 23, moreover, will serve to close the upperportion of slot 3, so that the entrance of warm air into the outerreceptacle or can above the level of the ice contained therein isprevented. The dished bottom 4 of said receptacle or can serves tostrengthen the same, as will be apparent, and also constitutes aslightly yielding support for the inner receptacle, which latter has itsbottom preferably formed with additional supports 24, said supports,however, being of less length than the main pivotal support 6. Thefreezer, as a whole, may readily be carried from place to place by meansof a bail 25 or similar device.

As further regards the two supports for the ends of the gearing frame,namely, the seat 1 and the opening 2, it may be stated that thesesupports are relatively movable, owing to the inherent resilience of theouter receptacle or can, to lock or unlock said ends, such movementbeing due to the elongation or expansion of the can incidental to theattachment to or detachment from the same of said frame. It may also bestated that during the time that the cover is in place such expansion isprecluded, owing to the tight fit of the cover.

I claim as my invention:

1. The combination, with a yieldable outer receptacle provided with apair of supports;

of an inner receptacle arranged within the outer receptacle; and agearing frame extending across said outer receptacle and associated withthe inner receptacle, said frame having its ends removably engaged withsaid supports and held in such engagemept by the resilience of saidouter receptac e.

2. The combination, with a yieldable outer receptacle provided with apair of supports; of an inner receptacle arranged within the outerreceptacle; and a gearing frame extending across said outer receptacleand associated with the inner receptacle, said frame having its endsremovably engaged with said supports, the distance between said endsbeing greater than that between said supports, to expand said outerreceptacle incidental to such engagement and to hold said frame againstdisplacement by the tension exerted thereon.
